Am fine tuning my old script.... I found the following command in my script to find the md5sum,

md5sum filename | cut -f1

Removed the cut from it, and used split in that place by which i avoided thousands of child process creation. ( am i right ?? it will create if i use ? )

As i understand this md5sum will also create new processes for the processed files. At an average this script processes thousands of files, so i have reduced the 2000 process to 1000 process. But i wonder, do i really want to execute md5sum command, or any other way to find out the md5sum value..

Note:

1. i checked for md5sum module, but i dont think any default module is available.. ( pls dont suggest modules available other than standard modules which comes with perl )

2. Or can we use the one md5sum command ( single process to find out md5sum for all files ) to find all files, and then use it my script ?
